This book deals with arid and semi-arid environments and their classification, and the physiological restraints and adaptations of plants to the environment. Further, it discusses economic botany and the needs and methods of conserving economic plants. A broad view is taken regarding the definition of economic plants, taking into account their value to the environment as well as to man and to livestock. The individual deserts and associated semi-arid regions are described in separate chapters, providing background information on the regional environments in terms of climate and major plant formations. The economic plants within these formations, their usages, geographical distribution together with their morphological and physiological adaptations are treated in detail.

Changing desert areas for land use implies a lot of ecological problems. These and related ones are dealt with in this book covering various interdisciplinary and international aspects. Large areas in arid and semi-arid regions are already polluted in various ways. One of the biggest problems is the anthropogenic salinization by inadequate means of agriculture and irrigation. Additionally, most arid areas in the world are dramatically overgrazed. Methods and practices of a sustainable land use in deserts are urgently needed in many arid regions. This book gives a broad survey on some of the affected regions of the world as well as some case studies from elsewhere (Aral Sea, Negev desert, Namib desert etc.). Thus, basic and applied sciences are brought together. Water management in deserts, grazing systems or reclamation of desertified areas are among the topics of this book, as well as social and economic aspects.

This is the second part of a two-volume work which presents an authoritative world-wide view of our knowledge about, and understanding of, hot-desert ecosystems. This includes some semi-arid and arid areas, as well as deserts in the strict sense. The hot deserts are distinguished from the temperate deserts (which form the subject of another volume in the series) by the virtual absence of snowfall, even though frosts may occur. For each major hot-desert region, expert authors have summarized existing knowledge according to a general outline. This includes descriptions of the ecosystem components (climate, soil, flora and fauna), and discussion of interaction between components and overall ecosystem functioning. The information from the regional chapters has been integrated into a world-wide view in the ''synthesis'' chapters. Because of its length, the volume is published in two parts. The first part included the general synthesis chapters, and regional descriptions of the hot deserts of America and Australia. The present volume covers hot deserts of Asia and Africa.

A desert is an ecosystem in an arid zone in which sand dunes cover the land and sandstorms often occur. Although desert vegetation is sparse, it plays an important role in ecosystem structure and function. Desertification is one of the most severe environmental problems today. Land desertification can be controlled through many measures, such as eco-villages, eco-agriculture, biodiversity conservation, and the combination of engineering and biology. This edited volume provides new insights into the pattern of desert ecosystems and the progress of desertification control. It is a useful resource for researchers in ecology, forestry, and land desertification control.

This book provides an overview of arid and semi-arid lands conditions, their general characteristics, methods of management, conservation, exploitation and reclamation. It also focuses on how to utilize the potential of arid lands with the minimum manipulation and alteration. Arid and semi-arid areas represent a major part of natural ecosystems not only in Iran, but around the world, and mismanagement and inappropriate exploitation of these areas may lead to further gradual degradation. As such, an understanding of the characteristics of these areas is vital if they are to be conserved and reclaimed.

Cyanobacteria have existed for 3.5 billion years, yet they are still the most important photosynthetic organisms on the planet for cycling carbon and nitrogen. The ecosystems where they have key roles range from the warmer oceans to many Antarctic sites. They also include dense nuisance growths in nutrient-rich lakes and nitrogen-fixers which aid the fertility of rice-fields and many soils, especially the biological soil crusts of arid regions. Molecular biology has in recent years provided major advances in our understanding of cyanobacterial ecology. Perhaps for more than any other group of organisms, it is possible to see how the ecology, physiology, biochemistry, ultrastructure and molecular biology interact. This all helps to deal with practical problems such as the control of nuisance blooms and the use of cyanobacterial inocula to manage semi-desert soils. Large-scale culture of several organisms, especially "Spirulina" (Arthrospira), for health food and specialist products is increasingly being expanded for a much wider range of uses. In view of their probable contribution to past oil deposits, much attention is currently focused on their potential as a source of biofuel.

This book complements the highly successful Ecology of Cyanobacteria and integrates the discoveries of the past twelve years with the older literature.
